Buggy code:
public class profileRule extends RewriteRule { private static Log log = Log . getLog ( profileRule . class ) ; @ Override public RewriteMatch matches ( HttpServletRequest request , HttpServletResponse response ) { String uri = request . getRequestURI ( ) ; String contextPath = request . getContextPath ( ) ; if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( "run<seq2seq4repair_space>called<seq2seq4repair_space>with<seq2seq4repair_space>" + uri ) ) ; } if ( ( uri . startsWith ( ( contextPath + "//profile" ) ) ) && ( request . getMethod ( ) . equalsIgnoreCase ( "GET" ) ) ) { if ( ( request . getRemoteUser ( ) ) != null ) { if ( uri . equals ( ( contextPath + "//profile//currentorder" ) ) ) { if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( contextPath + "//profile//currentorder<seq2seq4repair_space>matched" ) ) ; } return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { request . getRequestDispatcher ( "//ProfileController?action=currentOrder" ) . forward ( request , response ) ; return true ; } } ; } if ( uri . equals ( ( contextPath + "//profile//detail" ) ) ) { if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( contextPath + "//profile//detail<seq2seq4repair_space>matched" ) ) ; } return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { request . getRequestDispatcher ( "//ProfileController?action=detail" ) . forward ( request , response ) ; return true ; } } ; } if ( uri . equals ( ( contextPath + "//profile//feedback" ) ) ) { if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( contextPath + "//profile//feedback<seq2seq4repair_space>matched" ) ) ; } return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { request . getRequestDispatcher ( "//WEB-INF//profileFeedBack.jsp" ) . forward ( request , response ) ; return true ; } } ; } if ( uri . equals ( ( contextPath + "//profile//mycomment" ) ) ) { if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( contextPath + "//profile//mycomment<seq2seq4repair_space>matched" ) ) ; } return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { <START_BUG> request . getRequestDispatcher ( "//WEB-INF//profileComment.jsp" ) . forward ( request , response ) ; <END_BUG> return true ; } } ; } if ( profileRule . log . isDebugEnabled ( ) ) { profileRule . log . debug ( ( contextPath + "//profile<seq2seq4repair_space>matched" ) ) ; } return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { request . getRequestDispatcher ( "//ProfileController?action=profile" ) . forward ( request , response ) ; return true ; } } ; } else { return new RewriteMatch ( ) { @ Override public boolean execute ( HttpServletRequest request , HttpServletResponse response ) throws IOException , ServletException { response . sendRedirect ( ( ( request . getContextPath ( ) ) + "//" ) ) ; return true ; } } ; } } return null ; } }

Fix:
request . getRequestDispatcher ( "//ProfileController?action=comment" ) . forward ( request , response ) ;
